IMPROVEMENT IN. WIND-ENGINES;

Specification forming part of Letters Patent No. 209.94%, dated November12, 1878 application filed September 28, 1878.

To all whom it may concern:

Be it known that I, DAVID C. WALLING, o Kendallville, in the county ofNoble and State of Indiana, have invented a new and valuable Improvementin Windmills; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawings is a side view, part sectional, of my windmill.Figs. 2 and 3 are perspective detail views, and Fig. 4 is a view of thecap B.

.The nature of my invention relates to that class of machines whereinwind is utilized as a motive power.

The novelty consists, first, in the adaptation and arrangement of thegovernor relatively to the rudder or vane; and, secondly, in a cappedsleeve, perforated longitudinally to receive the piston-rod, havingradial longitudinal flanges, which are received and secured between thetimbers of the derrick, to prevent rotary motion, and provided with arecess in its upper surface adapted to receive a lubricant, and withinthis recess an annular shoulder furnishes a bearing for a correspondingshoulder upon the revolving frame. This cap is rigidly secured to thetop of the derrick, and furnishes the complete bearing for theoscillating wind mechanism.

Referring to the drawing, upon a suitable derrick, A, is rigidly andfirmly secured a capped sleeve, B. representing 'the cap, and B thetapering sleeve. Radial flanges b,-run ning longitudinal with the planeof the sleeve 13', are received between the timbers, and, bein gsecurely bolted thereto, prevent rotary movement of the cap, which capfurnishes the bearing for the engine and comprises the base of theturn-table. Upon theupper surface of the cap B is an annularupwardly-extending flange, I), of larger diameter than the diameter ofthe upper end of the sleeve, and also an annular shoulder, W, for thecorresponding bearing-shoulder a upon the rotating frame 0 orturn-table.

This turn-table O is of about quadrilateral form, and from it extends,on opposite sides, brackets D and E, on the former of which I journalthe wind-wheel W, and on the latter I journal the horizontal shaft f, ofthe governor F. A lateral projection, e, on the bracket E provides abearing for the lower end of the vertical standard 9 of the vane G,andthe upper end of said vertical standard is formed hollow, andreceives a thumb-screw, ac, which passes througha projection, a, on theframe 0. Y

Upon the bracket E, and on the side next the tail-vane, is a lug, 6,against which a corresponding lug, g, on the vane G abuts when thegovernor is at rest. A sleeve, f receives a rod, f which is renderedadjustable by means of a set-screw, f and which carries a weight, f*. Asleeve, f receives an adjustable eyepin, f, to which is looselyconnected a link, f which extends to the vane.

It will thus be observed that my governor is adjustable in threedifferent places, and that by this construction a greater scope ofchoice is allowed the operator to regulate the power to correspond withthe wind required.

Upon the inner end of the wind-wheel shaft to is an eccentric, H, whichcarries a pitmanconnection, .I.' J represents the pitman-rod. These areof ordinary construction, and no claim is made for them herein.

A projection, 9 upon the inner end of the vane G is adapted to abutagainst the frame 0 whenthe governor is in full force. It will beobserved that the play of the vane is nearly ninety degreesthat is tosay, the projection 9 abnttin g against the projection 0, holds the vanea little away from a right angle with the plane of the wind-wheel whenthe governor is at rest, and the projection 9 abutting against the frame0, holds the vane a little away from Y a parallel with the plane of thesaid Wheel.

K represents a stationary pulley, over which passes a cord, wire, chain,or the like, one end of which is secured to the rod f of the governor F,and the other extends downward in the derrick.

The operation of my invention is obvious.

The governor may be operated from below, either to gage the speed orpower or to enlongitudinal flanges b, made of one piece of metal, andadapted to serve in combination with the derrick-frame and rotatingframe, as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

DAVID 0Q WALLING.
